Victorian water supply companies, such as Coliban Water , are now enforcing regulations on the installation of backflow devices.
These devices ensure that when water is under pressure it flows “forward” and not “ backward “ so as not to pollute the main water supply. If polluted water enters the main water supply it can pose a serious health risk. In a domestic environment this could relate to drinking and bathing water. In a commercial environment backflow devices prevent contamination from chemicals and bacteria.

Many commercial properties will already have Backflow Devices installed but these are required to be tested annually to ensure they operate effectively.
